Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnifier which is used by being attached to the front portion of eyeglasses when performing fine manual work such as surgery.

[0002]

2. Description of the Related Art Surgeons who perform surgery often work with a magnifying device, and it is impossible to perform work without this magnifying glass, especially in operations such as cranial nerves and heart that are difficult to see with the naked eye. By the way, conventionally, the magnifier is hung on the face and fastened to the head with a rubber band, and if the person wearing the glasses wears the magnifier on the glasses, the magnifier is tightened to the head with the rubber band. . That is, the magnifier is fixed to the front of the spectacle lens with a rubber band, and when the magnifier is not needed, it is removed from the head together with the rubber band.
In order to prevent blood from splashing and getting into your eyes during surgery,
Even people with good eyesight often wear glasses with glass.

By the way, there are cases where a magnifier is necessary during surgery, and sometimes it is more convenient to perform surgery with the magnifier removed. With the conventional rubber band system, it is possible to hang or remove each time. Be troublesome. Further, since the magnifier is in contact with the curved spectacle lens, the positions thereof are not fixed, the directions of both magnifiers are not fixed, and the magnifier is often used in a state in which the magnifier is out of focus.

Therefore, the applicant has filed a patent application for "glasses with a magnifying glass" as of June 9, 2000 (Japanese Patent Laid-Open No.
1-350123). By the way, the glasses with a magnifying glass are "a link body is extended from the front part, and an arm having an arm piece extending to both sides is attached to the tip of the link body. The distance between the mirrors can be changed. "

Therefore, since the magnifier is integrally combined with the glasses, special glasses to which the magnifier is attached must be prepared, which is uneconomical for a person who wears glasses all the time. is there. Another problem is that the magnifying glass must be replaced every time the visual acuity changes.

[0006]

As described above, the conventional glasses with a magnifying glass have the above-mentioned problems. The problems to be solved by the present invention are these problems, and provide a magnifier for glasses which can be easily attached to the front portion of the glasses so that the magnifier can be easily attached and detached.

[0007]

The magnifier according to the present invention has a structure which can be used by being attached to the front portion of eyeglasses, and has a clip portion for sandwiching the front portion. A link body is extended from the clip portion, an arm is attached to the tip of the link body, and a magnifying glass is attached to the arm. The arms extend to both sides of the link and the magnifying glass is slidable along the arms. That is, the distance between the two magnifying glasses can be adjusted. And a screw is provided for fixing at an appropriate position.

By the way, the above-mentioned link body is constructed by connecting a plurality of links, and each link is bendable via a shaft screw. Therefore, by bending the link, you can adjust the distance between the magnifying glass, the front part, and the eyes.
Also, the vertical and horizontal directions of the magnifying glass can be adjusted. If unnecessary, the link body can be bent and flipped up above the front portion.

The clip is provided with two clip pieces forming a pair so that the left and right lenses can be sandwiched, and the clip pieces cover a soft rubber tube so as not to scratch the lens surface. Further, in order to fit the curved surface of the lens, the shape is not straight but curved or bent appropriately. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0010]

1 is a front view and FIG. 1B is a side view showing an expander according to the present invention. In the figure, 1 and 1 indicate a magnifying glass, 2 indicates a clip portion, and magnifying glass 1a and 1b indicate arms 3a and 3b extending in the left-right direction
Is attached to the screw via screws 4a and 4b.
By loosening 4b, the position of the magnifying glass 1a, 1b can be changed to the arm 3
It can slide along a and 3b.

Links 5 and 6 are connected to the center of the arm 3, and the clip portion 2 is attached to the end of the link 6. The clip portion 2 has two clip pieces 7a, 7b forming a pair at a predetermined interval and extending downward. The clip piece 7a on the front side is straight, but the clip piece 7b on the rear side is curved so that it fits on the lens surface when sandwiching the lens.

A spring is attached to the click portion 2 so that both clip pieces 7a and 7b forming a pair are always urged by a spring force in the closing direction, and the soft rubber tube 8 is attached to both clip pieces 7a and 7b. , 8 are coated so as not to scratch the lens surface when the lens is sandwiched.

2 and 3 show the case where the magnifier of the present invention is attached to the front portion 9 of the glasses. The two clip pieces 7a and 7b are mounted on the rim of the front portion 9 of the lens 1
With 0 inserted, the expander can be installed stably. By the way, the positions of the magnifying glasses 1a and 1b can be freely changed so that fine work can be easily performed, and the positions (height) in the up-down direction with respect to the flon portion 9 are clip pieces 7a and 7a sandwiching the lens 10.
It can be adjusted by the position of b.

The positions in the left-right direction and the two magnifying glasses 1
For the distance between a and 1b, loosen the screws 4a and 4b,
It can be adjusted by sliding along 3b. The horizontal direction of the magnifying glass 1a, 1b is the same as the screw 4
It can be adjusted by loosening a and 4b, and the vertical direction can be adjusted by changing the inclination of the link 5. That is, the tip shaft 1 of the link 6 extending from the clip portion 2 to the front surface
The inclination of the link 5 connected to 1 can be changed, and the inclination of the arm 3 attached to the tip shaft 12 of the link 5 is changed. Therefore, the vertical direction of the magnifying glass 1a, 1b can be freely adjusted and can be flipped up when unnecessary.

FIG. 4 shows another embodiment of the magnifying glass of the present invention, in which telescopes 13a and 13b are attached instead of the magnifying glass. The telescope 13 can view the object more magnified and can change the magnification rate.
Therefore, it is suitable for more detailed work. The other structure is common to the case described in FIG. 1 and therefore omitted.

FIGS. 5 and 6 show the case where the magnifier shown in FIG. 4 is attached to the front part of the eyeglasses by clipping. This is also common to the cases described in FIGS. The description is omitted. As described above, the magnifier according to the present invention is detachably attached to the front part of the glasses, and the following effects can be obtained.

[0017]

As described above, the magnifying device of the present invention can be attached by sandwiching the lens of the front part of the eyeglasses which is always worn. It can be attached at any time when a magnifier is needed for operations such as surgery, and can be removed when unnecessary. Further, since the magnifying glass is connected to the clip portion via the link, it can be flipped up and the position of the magnifying glass such as the interval and direction can be freely adjusted.

The magnifier of the present invention is convenient and economical because it can be attached to one's own glasses. And it is very easy to use compared to the case of hanging it on the head with a conventional rubber band. The magnifying glass is attached to an arm supported by a link, and it can be set to the most legible state by moving to an appropriate position and changing its direction.
